ANB WASTE COCK.

Patented Jan. '7, 1908.

Application filed April I0. 1907. Serial No. 357,450,

1o mi whom 'it may concern:

Be it lrnown that I, W ELDON P. DnvnRELL,

Decatur, in the county of Macon end State oi' Illinois, have invented certain new and uscful Improvements in Compression Stop and aste Cocks; and my preferred manner of carrying out the invention set forth in the following i'iill, clear. and onset description, terminating with claims particularly specifyingr the novelty.

lhis invention relatiesl to wntor distribution, and more especially to cocks :ind hun cets, and the object of the sinne is to produce an improved compression l:ind waste cock wherein either' the mein stein or the wnstc Stem is forciblyclosed and the cock operates against the pressure oi" the water or other luid ngent flowing therethrough.

To this end tho invention consists in the construction oi parts set forth herein, claimed below, and shown in Athe accompanying drawinvs, wherein figure l is a longitudinali section through this cock showing both voives in i'ull lines ns closed and the mein valve in dotted lines es open. Fig. is :i simiinr view showing the Waste valve open and the mninvelve ciosed and held in that position. Fig. $5 is n plan view of the casing. Fig. i is o reni' elevation of the nut and stems.

The casing e whole is designated es l, and it has inlet-end .Z-nnd outlet end Si, un intermediete u )right barrel 4 thi-ended for the cap 5, and n ottoni outlet or waste oriiico o here shown as between the outlet :ind they axial line of seid barret. lntrriorly il. is cored t'o admit the liquid et T to thcI lower end of the barrel below the moin vulve sont PS, and to let it out :it 9 nzleve seid sont. Above the outlet opening` 9 the bore ol" 'thc btirrcl hns a guide l() lor a purpose to appear hereinafter. Partially into one Well oi thc borrel is and in direct line and cornnnmitmtion with the orifice 6, asseen in Fig. 3'; ond below the outlet 9 is preferably formed n supplemental e casing thus far described is preferably in one casting.

Fitting ioosely but closely within the bnr- 20 preferably cupped et its `upper end to receive :in exponsive spring 2i which stands between the nut and the cop. The nut has un cnr 22 projecting from its rear side (see Figs. 3 and e), and

through this ear passes the up er end of the stern 23 of the Waste valve 24, t 1e letter nurnbcr designating the head which is adapted to be forced downward upon und close the waste orifice The stein may beheld in the ear by any moons, es by screw1 25; and stem and enr ond volvo vmove vertically Within the passage l1. r.lhreaded through the nut as et 33 is the stein 33 ot the moin valve 34, the letter number designating the heed which is adopted to be forced downward upon and close against the moin valve scat 8. Above the threads .'32 the main stem has n shoulder 35 adopted to strike within the cop .3, and, es usuel, the stein projects through the letter and carries n handle 37 which is removably attached thereto, ns by a, screw 3S.

With this construction, the operation is es follows: when the cock entirely closed, :ill ports stond ns soon in full lines in Fig. 1. To open the main volvo thc handle 37 is so turned that the threads 3; drow the mein stern upward through thc nut, reise the mitin valve trom its sont und ullow thc liquid to flow and lil't thc shoulder 355 :iguinst the cap. The lutter movement presses thc nut down word and closes the waste vnlvi` upon its sont. To :Lguin close thel nmin volvo, the operation is reversed. But in this reverso operation thel rotation ol the moin stom vlimtlly smits the umin vulve upon `its sont, :ii'tcr which :L further rotation ol' this stem rziiscs thel nut within tho borrel until the upper end oi the nut strikes thc cup und the moin Vnlvc is ,ground upon its sont, whcrcns th(` waste volvo is open. 'lhus it will be secu th-.it thel rotation oll n sngh` stein within rcrtnin limits opens one vitlvi` :uid closes the other or vico versn, permits botlrvnlrcs to romain closed nssistcd by the spring, ond :illows thc lutter to oil'set thc wntcr pressure. ltotntion ot' this stem beyond those limits grinds thc moin valve upon its sont, tho grindinlf nssistcd by tln` spring und positively op ioser by the cop.

'Vliet is claimed as new is: l. In n cock, n casing having inlet and ou tlot ends und a lutcrol orifice in-onc of them,

n borrel between said ends ond having openinUs into them and to seid orilire, und a vulve sont in the bnncl combined with u nut movable within the. ban-rol, n mein stom threaded through the nut und lntvinpr n hund ndnpted to coninct with suid sont, und a secondary stom rurricd by thc nut :md buving e head adopted to close said oriiice.

l a shoulder, on the stein', the shoulder abutting against the cap when one'yalve is closed an the other opefnangl the upper end of the hut abiitting against the cap when theI position of the valves is reversed.

'3. in a cook, a casing bomprising a barrel having inlet and outlet andan orifice in one of them, a valve seat in said barrelyand a ca combined With a nut movable Within t e barrel and having a eup ed upper end, a s ring between the cup and cap, a main stem t readed through the nut and having a head adapted to Contact with said seat, a secondary stem Carried by the nut and adapted to close said orificel and a guide in the barrel eveee toward which the nut is normally borneby said spring.

4, In a cock, a easing having inlet and out let ends and an intermediate barrel With openings into said ends and a valve seat be tween them, one Wall of the barrel having a passage parallel With lits axis and interseoting the outlet opening, and a Waste oriiee communicating with said passage; combined with a nut movable in the barrel and having an ear movable in its passage, a main stein threaded through` the nut and hav-ing a head adapted to Contact With said seat, a secondary stem carried by said ear and having a head adapted to close saifd orifice, and means for turning the main stern in either direotion. In testimony whereof' I have hereunto sub scribed my signature this, thegiiith day of WELDON P. DEVERELL. l/Vitnesses.
